Obesity remains a serious health problem and it is no secret that many people want to lose weight. Behavioral economists typically argue that “nudges” help individuals with various decisionmaking flaws to live longer, healthier, and better lives. In an article in the new issue of Regulation, Michael L. Marlow discusses how nudging by government differs from nudging by markets, and explains why market nudging is the more promising avenue for helping citizens to lose weight.

Two long wars, chronic deficits, the financial crisis, the costly drug war, the growth of executive power under Presidents Bush and Obama, and the revelations about NSA abuses, have given rise to a growing libertarian movement in our country – with a greater focus on individual liberty and less government power. David Boaz’s newly released The Libertarian Mind is a comprehensive guide to the history, philosophy, and growth of the libertarian movement, with incisive analyses of today’s most pressing issues and policies.

Fears of Nuclear Terrorism

Nightmare scenarios of terrorists gaining possession of nuclear weapons might make for good movie plots, but Americans grossly exaggerate the likelihood that an act of nuclear terrorism will occur within the next five or ten years. So says the RAND Corporation’s Brian Michael Jenkins in a new book, Will Terrorists Go Nuclear?(See also some of John Mueller’s writings on this subject here and here.)

Rather than telling Americans constantly to be very afraid, we should stress that even an event of nuclear terrorism will not bring this Republic to its knees. Some will argue that fear is useful in galvanizing people and concentrating their minds on this threat, but fear is not free. It creates its own orthodoxy and demands obedience to it. A frightened population is intolerant. It trumpets a kind of “lapel pin” patriotism rather than the real thing. A frightened population is also prone both to paralysis – we’re doomed! – and to dangerous overreaction.

I believe that fear gets in the way of addressing the issue of nuclear terrorism in a sustained and sensible way. Instead of spreading fear, our leaders should speak to the American traditions of courage, self-reliance, and resiliency. Heaven forbid that an act of nuclear terrorism ever actually occurs, but if it does, we’ll get through it.

It is understandable why politicians are reluctant to embrace such recommendations. On the other hand, if they understood that terrorists seek to engender panic, public officials would pay as much or more attention to calming the public’s fears as they do to stoking them.
